The aim of this study is to develop an understanding of and analyze how  different professionals interpret their roles, responsibilities, and collaboration in the provision of caregiver support in the context of dementia, as well as to examine how communicative and organizational factors may influence this collaboration. The study is based on a qualitative method involving eight semi-structured interviews with professionals from four municipalities in southern Sweden. The collected material was analyzed using thematic analysis. The results show that the professionals view caregiver support as a shared responsibility, although their specific areas of responsibility differ clearly. Collaboration varies across municipalities and is influenced by limited knowledge of each other’s roles, resource constraints, and restricted information exchange between the professions. The study highlights the need for clearer collaboration routines, joint meetings, and early professional interventions for caregivers throughout the course of the illness. Future research should focus on how a more equitable and cohesive system of caregiver support can be developed and how caregivers’ participation in collaborative processes can be strengthened.
